Description

Technical Field

[0001] This utility model relates to the field of commutator technology, specifically to an easy-to-maintain commutator. Background Technology

[0002] Traditional commutators typically employ a monolithic design, with the commutator segments and base often fixed as a single piece or tightly bonded together using complex processes. While this monolithic structure ensures stability in the initial state to some extent, it reveals numerous drawbacks during long-term use. Due to the lack of disassembly capability, when problems such as loosening or wear occur at the connection between the commutator segments and the base, it is difficult to repair or replace individual damaged components. Often, the entire commutator needs to be disassembled and replaced, resulting in wasted resources and significantly increased maintenance costs. Furthermore, disassembling a monolithic commutator is cumbersome, requiring specialized tools and complex processes, consuming considerable time and manpower, and resulting in extremely low maintenance efficiency. In addition, the monolithic structure hinders internal cleaning and maintenance, allowing dust, moisture, and other impurities to accumulate, affecting commutator performance and shortening its lifespan. Therefore, there is an urgent need to design a commutator that is easy to maintain to address the problems associated with traditional monolithic commutator structures. Summary of the Invention

Therefore, they should not be construed as limitations on this utility model.

[0030] Please see Figures 1-5 The diagram illustrates an easy-to-maintain commutator comprising a base 1 and commutator segments 2. Two integrally formed connecting segments 3 are provided on one side of the commutator segment 2. Fixing grooves 4 at the upper and lower ends of the base 1 are sized to fit the connecting segments 3, achieving a stable connection between the connecting segments 3 and the fixing grooves 4 through an interference fit. This connection method is convenient to install and has a certain degree of stability. The upper and lower ends of the base 1 are provided with threaded holes 5. Each threaded hole 5 is threadedly connected to a clamping member 6. The connecting part 601 of the clamping member 6 is connected to the threaded hole 5, and the pressing part 602 can press the connecting segments 3 tightly, further enhancing the connection strength between the connecting segments 3 and the base 1. One end face of the pressing part 602 is provided with a disassembly groove 604 for easy removal with a Phillips screwdriver. The pressing part 602 also has four engaging force grooves 605 for easy removal with specialized disassembly tools. The two disassembly structures allow for selection of a suitable disassembly method according to actual conditions, further improving disassembly efficiency.

[0031] Multiple commutator segments 2 are arranged in a circumferential array on the outer ring of the base 1. Each commutator segment 2 has a connecting piece 3 connected to a corresponding fixing groove 4, ensuring the uniformity and stability of the commutator structure. A sealing ring 7 is provided between the clamping member 6 and the connecting piece 3 to prevent dust, moisture, etc. from entering and affecting the commutator performance. The clamping member 6 has a through hole 603 that penetrates the connecting part 601 and the pressing part 602, and the base 1 has a through hole 8 that penetrates the body. The through holes 603 and 8 have the same inner diameter and are coaxially arranged, which facilitates the installation of wires and other components, and also facilitates installation and disassembly. An insulating gap 9 is provided between adjacent commutator segments 2 to ensure insulation between each commutator segment 2 and prevent short circuits.

[0032] Working principle:

[0033] During installation, the connecting piece 3 of the commutator segment 2 is inserted into the fixing slot 4 of the base 1, and initially fixed using an interference fit. Then, by rotating the clamping member 6, the lower pressing part 602 presses the connecting piece 3 firmly onto the base 1, achieving a secure connection between the commutator segment 2 and the base 1. For maintenance, a Phillips screwdriver can be inserted into the disassembly slot 604, or a special tool can be used to engage the locking slot 605. By rotating the clamping member 6 in the opposite direction, the commutator segment 2 can be easily disassembled for inspection or replacement. The insulation gap 9 ensures that the commutator segments 2 do not interfere with each other, and the sealing ring 7 prevents external impurities from entering, ensuring the normal and stable operation of the commutator.
